Gtk.ListStore.prototype.move_before

function move_before(iter:Gtk.TreeIter, position:Gtk.TreeIter):void {
    // Gjs wrapper for gtk_list_store_move_before()
}

Moves iter in store to the position before position. Note that this function only works with unsorted stores. If position is null, iter will be moved to the end of the list.
